Replace the directive with the output of applying the view to the resultset
returned by the query stored in the bookmark. By default, the view is the one
stored in the bookmark, but it can be overridden by the directive as in the
example above.

“X eid %(userid)s” can be used in the RQL query stored in the Bookmark, for
this query will be executed with the argument {‘userid’: _cw.user.eid}.
